The Eternal Mangekyō Sharingan (EMS) is a form of the Sharingan that allows its user to overcome the blindness associated with using the standard Mangekyō Sharingan, which is crucial for maintaining combat effectiveness over time.

Unlike the typical Mangekyō Sharingan, which can lead to gradual blindness with excessive use, the EMS allows users to utilize their powerful abilities—such as Amaterasu and Tsukuyomi—limitlessly without deterioration of vision.

Itachi Uchiha, known for his exceptional skills, would have experienced a significant boost in reaction speed and combat efficiency with the EMS, allowing him to respond to threats faster than before.

The EMS does not grant new abilities; instead, it enhances the user's existing Mangekyō Sharingan techniques, making them more potent and sustainable during prolonged battles.

Itachi's mastery of the Tsukuyomi, which manipulates time perception and inflicts psychological trauma, would likely have reached new heights with the EMS, enabling him to cast it more effectively against opponents.

Susanoo, the protective spirit armor, would have also been improved, allowing Itachi to utilize the Perfect Susanoo, which offers more formidable defense and attack capabilities compared to his standard version.

The concept of "blood ties" is essential in obtaining the EMS, as the user must have a strong familial connection with the donor of the Mangekyō Sharingan.

Itachi's connection to Sasuke would have been significant for this purpose.

Itachi's chakra reserves were comparatively low, which limited his ability to maintain powerful techniques for extended periods.

However, with EMS, he could sustain his Susanoo and other abilities more effectively.

The Mangekyō Sharingan's techniques are often unique to each user, and while Itachi's abilities like Amaterasu and Tsukuyomi are powerful, they can also be countered by other advanced techniques in the Naruto universe.

The relationship between Itachi and Sasuke, characterized by deep emotional ties, would have amplified the effectiveness of their potential EMS connection, allowing for a stronger bond and better synergy in combat.

Itachi's potential with EMS could have placed him near the top tier of ninja, comparable to legendary figures like Madara Uchiha, who also possessed the EMS and showcased immense power.

The EMS is considered a rare achievement within the Uchiha clan, with only a few users known in the series, such as Sasuke and Madara, emphasizing its significance and the challenges associated with obtaining it.

Itachi's illness and eventual death limited his overall power, but an EMS Itachi would have had the advantage of longevity in battles, allowing him to utilize his abilities more freely without the burden of his health issues.

The psychological aspect of Itachi's techniques, particularly Tsukuyomi, involves manipulating the opponent's mind, which could lead to severe mental strain or incapacitation, showcasing the strategic depth of his combat style.

The Susanoo's form varies by user, and Itachi's version is unique in its ability to wield the Yata Mirror and Totsuka Blade, which are considered some of the most powerful tools in the Naruto universe.

Itachi's character embodies the theme of sacrifice and the weight of responsibility, and the potential for EMS could have deepened this narrative by allowing him to fully realize his capabilities while protecting his loved ones.

The EMS does not inherently make a user invincible; strategy, intelligence, and the understanding of one’s opponent are still critical components of combat in the Naruto world.

If Itachi had obtained the EMS, his role in the narrative could have shifted dramatically, possibly altering the outcomes of several key battles and the overall arc of the series.

The lore surrounding the Uchiha clan and the Sharingan is deeply connected to ideas of power and sacrifice, with the EMS representing both a reward and a burden for those who pursue it.

The mechanics of the Sharingan and EMS touch upon themes of genetic legacy and the consequences of power, reflecting deeper philosophical questions about the nature of strength and family ties within the narrative of Naruto.
